I have this new colony set up 3 females to 1 male, they are pews. Every female got pregnant. The first just had her litter of 13, the second had 6 yesterday. They have piled the babies and all three females are nursing them, even the one due in a few days. They seem to be sharing the babies, even the dad seams to be looking after them. Only two were eaten. Did I just get lucky with this colony or is this the norm?
